A premium quality ECC803 tube that replaces any 12AX7 / ECC83 tube type. The JJ ECC803-S is a warm, full sounding tube, with high-gain. It's great sounding in hifi amps and guitar amps (guitar players see note below).
Note: Because this tube has a long plate structure it is susceptible to excessive microphonics and is therefore not recommended for use in combo amps or high gain stages. For these amps the JJ ECC83-S is a better choice.
I put this tube in my Real Tube pedal and it worked wonders. It took all the shrill sound and lots of white noise away. Best in front of a clean channel.

Great Pre-amp tube in overdrive slot
I'm using this pre-amp tube in my V2 slot (Over Drive) of my Peavey Classic 50 Head. I'm getting the warmest fullest tone that cuts out most of the high's and brings in the bass and mids without being saturated and muddy. This Tube works wonders!

A really good current production pre amp tube
I'm currently using this tube as a phase inverter on a Leak Stereo 50 HiFi amp, and the JJ is a great sounding tube. No complaints at all, and it stacks up very well compared to a Philips 7025 USA made tube when tested in the same position. And for under $15, it's worth giving a try.
